LOCOMOTIV-BOTTOlVI-BINDER YOKE.I

Specification of Letters Patent. Patented Dec. 31d, 1918.

Application filed August 21, 1918. Serial No. 250,836.

T0 all whom it may concern:

Be it known that I, WILLIAM F. TURNER, a citizen of the United States, residing at Waycross, in the county of Ware and State of Georgia, have invented certain new and useful Improvements in Locomotive-Botthe following is aspecification, reference being had to the accompanying drawings.

This invention relates to locomotives, and particularly to the main frames of the trucks.

l The general object of the invention is to provide improved means for holding in place the pedestal brace or binder.

lHeretofore the pedestal braces or binders have been held in place by bolts. The holes for these bolts vweaken the bottom frame rail and the pedestal brace or binder unnecessarily, and an obj ect of my invention is to provide improved -means for holding the pedestal brace in place which will not involve the weakening of the lower frame rail.

A further object is to provide a construction of this kind wherein the pedestal brace or binder is held in place against the lower ends of the pedestals, by means of yokes, screws being used to urge the yokes in a direction to clamp the brace firmly in place against the pedestals.

A further object is to provide a construction of this character wherein yoke blocks are used and provide means to prevent the yoke blocks from turning.

Other objects will appear lin the course of the following description.

My invention is illustrated in the accompanying drawings, 'wherein 1'- Figure 1 is a side elevation, partly broken away, of a portion of the locomotive truck frame with my improvement applied thereto;

Fig. 2 is a section on the line 2-.2 of Fig. 1; and

Fig. 3 is an elevation of another form of yoke block.

Referring to these figures, 1() designates the usual truck frame for either the ordinary truck wheels or the locomotive driving axle. From the top frame rail extends the usual pedestals 11 and coacting with these pedestals is the pedestal brace or binder 12 which is formed with transverse grooves 18 or recesses to receive the lower projecting ends of the pedestals where they extend down below the lower frame rail.

For the purpose of holding the pedestal brace 12 in place, I provide a pair of yokes 1&1. Each yoke has a-lower body portion having a screw-threaded passage 15 and from the body extends the arms 16 which are spaced sufficiently far apart to embrace the pedestal braces and the lower frame rail 17. Disposed upon and resting upon the lower frame rail 17 is a yoke block 18, one for each yoke and extending transversely through vthis yoke block is a pin 19 which passes through apertures 20 formed in the arms 16.

This pin may be held against accidental displacement iny any suitable manner, but is preferably removable upon force being applied thereto.

Passing through the screw-threaded aperture 15 is the screw 21 having a head 22 at its lower end, whereby it may be rotated and adapted to be heldin adjusted position by means of the binding nut 23. The lower face of the block 18 is formed with a plurality of downwardly extending pins or lugs 25 arranged in pairs-and adapted to engage in recesses 24 formed in or extending through the rail 17. Preferably also the frame is formed with a fillet a, and the block 18 is rounded to conform to this fillet. The binder 12 is also formed with a dowel pin 25'r1 entering a suitable recess in the rail 17. j In Fig. 3 I show` another form of yoke block, designated 18a wherein the pin' 19 rests in a semi-circular recess 26 formed in the top of the yoke block.

-It will be understood, of course, that the 'driving box or other axle box is intended to be supported in the space defined by the pedestals 11 and between the top frame rail and the binder or brace 12. It is an easy matter to dispose the pedestal brace or binder 12 in position and then engage it in place by means ofthe yokes 14 and the yoke blocks 18 or 18a. Then the screws 21 may be turned to bear against the lower face of the pedestal brace' or binder, thus locking the parts in firm engagement. It will be seen that with this construction the lower frame rail andthe binder are neither of them perforated -for the passage of bolts or like fastening devices, and thus neither of these parts is weakened as it otherwise would be. The binder is held from any longitudinal lmovement but at the same time may be readily removed by driving out pin 19 when necessary or readily re- While I have illustrated a form of my invention which I believe to be thoroughly satisfactory in practice, it will, of course, be understood that minor changes may be made in the details of construction without departing from the principle of the invention.

I claim l. In a locomotive, the combination with a top frame rail having depending pedestals and a lower rail, of a pedestal brace or binder coacting therewith, and vertically extending yokes embracing the ends of the binder and detachably engaging over the lower rail of the frame and holding the binder in place.

2. In a locomotive, the combination with a top frame rail having depending pedestals, of a pedestal brace or binder coacting therewith, and yokes embracing the frame and the binder and detachably engaging with the frame and having screws bearing against the binder.

3. In a locomotive, a top frame rail, depending pedestals, and a. bottom frame rail, a pedestal brace or binder engaging' the lower ends of the pedestals, yokes having each a screw-threaded body and parallel arms Vadapted to embrace the ends of the binder and extend above the lower frame rail, a block for each yoke resting upon the lower frame rail, a cross rod, extending through said block and the upper ends of the arms, body of the yoke and engaging the lower edge of the binder.

4. 4In a locomotive, a. top frame rail, depending pedestals, and a bottom frame rail, a pedestal brace or binder engaging the llower ends of the pedestals, yokes having each a screw-threaded body and parallel arms adapted to embrace the ends of the binder and extend above the lower frame rail, a block for each yoke resting upon the lower frame rail, a cross rod extending and screws passing through the through said block and the upper ends of the arms, screws passing through the body of the yoke and Vengaging the lower edge of the binder, and a lock nut on each yoke screw, the block being provided with lugs Vengaging in recesses in the upper face of yokes embracing the ends of the binder and y extending above the lower frame rail, a

block for each yoke resting upon the lower frame rail and having dowels inserted Vin said sockets, and meansdetachably connecting the blocks to said yokes.

6. In a locomotive, a top frame rail, depending pedestals, a body frame rail, -a pedestal brace or binderengaging the lower ends of the pedestals, the bottom frame rail on each side of the pedestals having vertically extending sockets, yokes, each having a screw-threaded body, and parallel arms adapted to embrace the ends of the binder and extend above 'the lower frame rail, a block for each yoke resting upon the lower frame rail and having dowels extending into said sockets, a cross rod extending through said block and the upper ends of the arms, a screw passi g through the body of the yoke and engaging the lower edge of the binder, and means for locking the screws, the binder being formed with downwardly extending dowels engageable in said sockets. t

In testimony whereof I hereunto aix my signature in the presence of two witnesses.

WILLIAM F. TURNER.
